The type of a variable that is volatile is _______________*1 pointa) Volatile variableb) Mutable variablec) Immutable variabled) Dynamic variable

To determine the correct answer to the question about the type of a volatile variable, let's break it down:

1. Understanding Volatile Variables: In programming, a volatile variable is one that can be changed unexpectedly, typically in a multithreading environment. The volatile keyword indicates to the compiler that the value of the variable may change at any time, thus preventing certain optimizations.

2. Analyzing the Options:

   • a) Volatile variable: This directly matches the definition.
   • b) Mutable variable: While this refers to variables that can be changed, it's not specifically about the 'volatile' context and is more related to data structures.
   • c) Immutable variable: This refers to variables that cannot be changed once created, opposite of volatile.
   • d) Dynamic variable: Typically refers to variables whose storage is allocated at runtime, not specifically related to volatility.

3. Conclusion: Given the definitions and context, the best choice that reflects the nature of a volatile variable is clearly option a) Volatile variable.

Final Answer

The type of a variable that is volatile is a) Volatile variable.
